MUIC & ACOUTIC – BRA & WOODWIND INTRUMENT CALCULATOR
Recorder Fingering Freq
A precise tool.
What is the Recorder Fingering Freq & How does it work?
The frequency of a note produced by a recorder can be calculated based on the length of the air column within the instrument. The fundamental frequency ( f ) is given by:
f = frac{v}{2L}
v = speed of sound, L = length of the air column
The speed of sound in air is approximately 343 meters per second at room temperature. The length of the air column ( L ) can be adjusted by covering different holes on the recorder, which changes the effective length of the instrument.

Frequently Asked Questions
How do I calculate the frequency of a note on a recorder?
Use the formula f = v / (2L), where v is the speed of sound (about 343 m/s) and L is the length of the air column.
What is the speed of sound used in this calculation?
The speed of sound in air at room temperature is approximately 343 meters per second.
How does changing the holes on a recorder affect its frequency?
Covering different holes changes the effective length of the air column, which alters the fundamental frequency of the note produced.
Can this calculator be used for other wind instruments?
While similar principles apply, the specific calculations may vary for other wind instruments due to differences in their construction and playing techniques.
What is the fundamental frequency of a note on a recorder?
The fundamental frequency is the lowest frequency produced by a vibrating system, calculated using the formula f = v / (2L).
How does temperature affect the speed of sound in air?
Temperature increases the speed of sound. At 0°C, the speed of sound is about 331 m/s, increasing to approximately 343 m/s at room temperature (around 20°C).
Can this calculator help in tuning a recorder?
Yes, by calculating the expected frequency for a given air column length, you can compare it with the actual frequency produced to determine if your recorder is properly tuned.
